I am currently running a multistate design protocol (mpi_msd.linuxgccrelease) for bispecific antibody design. After I have run the protocol with my options, the program runs and is "stuck" at this point for a long time:
core.pack.pack_rotamers: built 39485 rotamers at 58 positions.
core.pack.interaction_graph.interaction_graph_factory: Instantiating DoubleLazyInteractionGraph
core.pack.interaction_graph.interaction_graph_factory: IG: 22325380 bytes
I understand from prior trials that the program will start producing generations after this point, but it is still stuck here. At this point, there is 20gb of ram usage, but generations are still not produced yet.
I am running Ubuntu 18.04, with Rosetta 3.8.
The options I have run here are as follows:
-chemical:exclude_patches LowerDNA UpperDNA Cterm_amidation SpecialRotamer protein_cutpoint_upper protein_cutpoint_lower VirtualBB ShoveBB VirtualDNAPhosphate VirtualNTerm CTermConnect sc_orbitals pro_hydroxylated_case1 pro_hydroxylated_case2 ser_phosphorylated thr_phosphorylated tyr_phosphorylated tyr_sulfated lys_dimethylated lys_monomethylated lys_trimethylated lys_acetylated glu_carboxylated cys_acetylated tyr_diiodinated N_acetylated C_methylamidated MethylatedProteinCterm
Would be grateful if someone could help me understand why the problem persists.
